含水率对福建森林草本植物燃烧碳排放的影响
Effect of water content on carbon emissions from combustion of forest herbaceous plants of Fujian.
为探究草本可燃物在不同含水率下的碳排放特性,本文采用自主设计的生物质燃烧和分析系统模拟不同含水率下福建省林下常见草本(福建观音座莲、芒萁、五节芒、莠竹)的燃烧过程,实时监测并计算烟气中含碳气体(CO2、CO、CxHy)和PM2.5 中碳质组分(TC、OC、EC)的排放因子,分析OC和EC之间的比值及相关性,比较不同碳排放物质的碳转化效率差异,揭示森林地面可燃物含水率变化对燃烧碳排放的影响。结果表明:①草本含水率对碳排放物质排放因子具有显著影响,随…查看全部>>
In order to investigate the carbon emission characteristics of herbaceous combustible materials under different water contents,this paper adopts the self-designed biomass combustion and analysis system to simulate the combustion process of widely distributed forest herbs in Fujian Province(Angiopteris fokiensis,Dicranopteris pedata,Miscanthus floridulus,and Microstegium vimineum)under different water contents,and monitor and calculate the carbon gas(CO2,CO,C…查看全部>>
